PHOTO: focus, strange isolation

Hi,
this image (link) has been rejected (no resubmit) for the following two reasons:

1. We found this image to be out of focus viewed at 100%.
2. The execution of isolation contains stray areas that are either too feathered or rough.

->1. The image has a large in-focus-area on my graphics monitor. How is it on your monitor?
->2. Yes, there are many stray pixels around the edge when I push she black levels slider to the right. But this is a strange phenomenon. I use photoshop cs6. The tiff-file has a clean edge:

Thanks Thomas.
I had rather a workflow problem than a photoshop problem, because this could be solved easier.
But how come the jpg-file ist fine after converting it from tif to jpg and it has those stray pixels after reopen it in PS?
I tried another image with 0.5 softness and have the same problem.

1. Don't worry about the faint JPEG artifacting you can detect on an isolated image. That's impossible to eliminate completely and the Inspectors do not run this kind of levels test on images - the inspection is based solely on bare-eyes analysis of the image at 100%.

2. The isolation here is way too hard-edged and is visibly jagged in places.

3. The image really should have also been rejected for the camera shake blurring visible in the image. That probably played a role in the No Resubmit. The Inspector should have clicked that reason as well.

It has a subtle blur to it but that is not missed focus. In places you can perceive a "streaming" effect, even if it is slight. For a shot like this that resembles a studio still life, the eye expects the object to appear at rest. This exact leaf photo, in its original context (falling from the tree) would be perfectly acceptable focus, even with more blurring than that, because it would make sense in that context.

Oh, and, yeah, I've been a photo Inspector here for nearly 10 years. Eagle eyes I do indeed have.

@donald_gruener:
I can‘t really see a "streaming" effect. But to know it is there, to pay attention to it, will help to train my eyes.
It would be great to have an in depth video-traing for inspecting an image. That would save inspectors and contributors a lot of time.
